Easy Salad with Spinach, Apples, Walnuts and Feta

I do like to eat a nice salad, especially for lunch.   Some of them are quite sophisticated and require a bit of preparation.  I like this one because it's super easy, quick and oh, so delicious!  Of course, you can substitute the apples with pears, feta with blue cheese, walnuts with pecans or cashews, spinach with romaine lettuce...  Or add grapes, tomatoes, croutons, chicken and anything else.  But I like it simple, just like this.  Easy, tasty and nutritious.  Enjoy!

Ingredients (for 1 person):
-2 cups baby spinach
-6 Tbs crumbled feta cheese
-1 apple, cored and chopped
-1/4 cup walnuts
-Caesar dressing
Place spinach on bottom of plate.  Top with remaining ingredients.  Toss and enjoy!
